| Abstract: | An iron-rich aluminosilicate liquid is studied in different atmospheres by using differential scanning calorimetry. The results show that the oxidation state of iron and the maximum temperature of the scan have an effect on the liquid structure and on the crystallization behavior of the liquid during both cooling and reheating processes. Increase in Fe2+/Fe3+ enhances crystallization and favors formation of a stable crystal structure. The structural order conserved in the liquid is an intrinsic phenomenon, which is not related to the oxidation state of iron. |
